Hosted Voice FAQ

What is VoIP, and how does it work?

Hosted VoIP is a telephone service that uses the internet to handle calls. The phone system itself is based in a data center and routes call traffic through internet connections. VoIP phone handsets can be plugged into any internet connection to gain access to the service.

Can I use my business’ existing phone number?

Yes, existing phone numbers can be ported from carrier to carrier, so there’s no need to update your business phone number.

What type of internet service bandwidth is required for VoIP?

Typically, hosted VOIP communications require between 60k–100k of bandwidth per call. That equates to 1 MB of internet bandwidth for 10 simultaneous calls.

What about service quality for VoIP?

Numerous factors can affect the service quality of hosted VoIP. While hosted VoIP technology has improved vastly in the last decade and call quality should be perfect, some factors can affect voice quality, namely the:

  • Internet connection (carrier and bandwidth).
  • Network switch or network traffic on the internal data network.
  • Firewall.

Where will my hosted VoIP phone service reside?

Can I plug a VoIP phone into my home internet connection and get a dial tone?

Yes, technically speaking, you can plug a VoIP phone into any internet connection and it should work. Occasionally, a misconfigured firewall can prevent the phone from getting the dial tone. For example, if you plugged it into a hotel data network, the traffic may be restricted by the hotel’s network firewall. Opening up the correct ports on your firewall easily solves this issue.

Is my hosted VoIP call encrypted?

A TLS protocol is required to encrypt voice traffic over the internet. As long as you are using this technology on your hosted VoIP service, your voice calls are encrypted.

What is the return on investment for hosted VoIP phone services?

We estimate the break even point for on-premises phone systems versus hosted voice PBX services is approximately 200 users. Our extensive cost analysis uses this number as a benchmark to advise clients on cloud-hosted voice options. If your business has fewer than 200 phone handsets, there is no question that a hosted voice solution is less expensive than an on-premises phone system.

Can I have my greetings professionally recorded?

Yes, this service is included with any migration.

What are the benefits of using hosted VoIP?

Cost savings is the primary benefit of using a hosted VoIP telephone service, especially for a small business of 1–150 employees. In a 10-year period, hosted VoIP services are 30–50 percent less expensive than an on-premises phone solution with monthly carrier charges and fees.

Hosted VoIP phone systems also offer advanced features and functionality, including automatic system upgrades. On-premises legacy phone systems must be manually upgraded, meaning time, money and potential construction at your business.
